The ImageMaster Compact from Trioptics GmbH is a motorized modulation transfer function (MTF) test station for prototype and small serial production. It is a horizontal tabletop instrument for analyzing the image quality via the MTF and for measurements of effective focal length, distortion and astigmatism. The result of cooperation between Trioptics and Wells Research, the system includes software. Because of its modular design, a variety of lenses and optical assemblies can be tested. Features include on- and off-axis measurements up to ±130° and easy switching between an infinity and a finite conjugate system. The collimator can be exchanged with a backlit source mounted on a motorized stage.
